Known SolarWinds NPM Issues

This version of SolarWinds NPM includes the following known issues:

Area Description
Active Directory The Email a Web Page alert action does not function as designed for users who are logged in to the web console using an Active Directory account or group. This is a known issue that may be addressed in a future release.
Alerts If you are using an Active Directory account for authentication into the web console, you may experience a session timeout when attempting to execute an Email a web page alert action.
To resolve this issue, wait for the session timeout to expire (this may take upwards of 20 minutes), and then restart the Alerting Engine service.
If you upgrade to NPM 11.5 on a server with NPM and SAM, some SAM-specific alerts might not be converted correctly. To resolve the issue, upgrade to SAM 6.2.
The "Alert me when volume has less than 60 days of capacity left" alert tracks interfaces instead of volumes when you upgrade from NPM 11.5 to NPM 11.5.2.
Auditing The default Auditing Trails Retention setting value (365 days) may result in an excessively large auditing table and significant database performance issues.
  To resolve this issue, log in to the web console as an administrator, click Settings > Polling Settings, and then change the default Auditing Trails Retention value.
  Note: You may also reduce the size of the auditing table in your database by opting to audit fewer event types.
Charts On upgrade to the new format, old format charts with the setting Time period for Chart set to Last 2 Hours may have the configured time period changed.
  To resolve this issue, reconfigure the Time period for Chart setting to Last 2 Hours for all affected charts.
Charts that are included in new web console reports are not currently available for export to .XLS. This capability is expected in a future release.
Custom Properties Custom property export to .XLS fails when a Definition column is included. For more information, see this article.
Discovery Due to an issue with its SNMP agent, KYOCERA MITA Printing Systems (OID: may not be recognized correctly.
ESX Monitoring When adding or updating an ESX server as a monitored node, you may need to refresh the view before successfully changing the provided IP address.
FIPS SolarWinds installations on Windows server 2008 R2 and Windows 7 require a Microsoft hotfix to realize the FIPS-compatibility features of SolarWinds products. For more information about this required Microsoft hotfix, visit Microsoft support pages.
Groups The Add New Group button is not available on the Manage Groups of the web console when it is viewed using Google Chrome browser with the AdBlock plugin.
Hardware Health Hardware health category with disabled sensors is not updated correctly when a hardware health node is assigned to an Additional Poller.
Interface Indices Interface indices are maintained in both the Interfaces table and the NPM_Routing table of the SolarWinds database. Because these tables are polled on different polling intervals, the same interface may have different indices in each table as interfaces are remapped on independent polling intervals.
IPv6 For installations of SolarWinds NPM on Windows Server 2008 R2, if Link Local IPv6 addressing is enabled, only IPv4 addresses may be obtained. For more information, see this article.
NTA Integration Settings for resources specific to NetFlow Traffic Analyzer (NTA) are not available for editing when NTA resources are included in new web console reports.
Network Atlas Under certain specific conditions, Network Atlas may fail to complete file synchronization with the SolarWinds database. This failure has been linked to Network Atlas users who have insufficient permissions to access the Network Atlas synchronization folder. Confirm that the user logged in to Network Atlas is able to access the Network Atlas synchronization folder.
Nodes Non-Cisco nodes may not display operating system versions in Node Details resources.
Nodes are not assigned individual pollers if a discovery profile that was created before upgrade is used.
Polling Engines In environments using multiple polling engines, it is not currently possible to directly select an object's polling engine as a grouping criterion ("GroupBy") for custom resources and reports. It is, however, possible to use the Dynamic Query Builder in Advanced Mode to create conditions and filters based on PollingEngineID. Direct grouping by polling engine is expected to be available in a future release.
Quality of Experience As a general rule of thumb, for up to 1 Gbps of traffic, 2 CPU cores, at minimum, are required, and an additional 1 CPU core and 1 GB RAM are required for every 100 Mbps of traffic. Accordingly, for example, you should use:
   - 3 CPU cores + 1 GB RAM to effectively process 100 Mbps of traffic
   - 7 CPU cores + 5 GB RAM to effectively process 500 Mbps of traffic.
   - 11 CPU cores + 9 GB RAM to effectively process 900 Mbps of traffic.
In selected locations in the web console, Transactions per Minute are displayed with ms as units. This condition may be corrected in a future release.
Reports Sorting by title is not currently available for Interface Availability reports.
SolarWinds Orion EOC reports must not have the same name as existing NPM reports.
Report logos are not displayed correctly when the report is created in a web console running on Internet Explorer 7.
Charts that are included in new web console reports are not currently available for export to .XLS. This capability is expected in a future release.
When using SWQL to build a custom report, ORDER BY conditions are not respected. Data may be sorted from the Edit Table view for the affected report.
Routing Data OSPF/BGP neighbor status is not currently supported for monitored IPv6 nodes.
Security Using a Password as a Key is not available for SHA1 authentication. As SHA1 authentication is the only FIPS-compatible method, the Password as a Key option is not available for FIPS-enabled environments.
SolarWinds Toolset Integration The SolarWinds Toolset Integration for the Orion Web Console is unable to install automatically on Windows Server 2008 R2 due to an Internet Explorer version 8 (IE8) security feature. As a result, whenever the web console opens a view containing resources that can use the Toolset integration, a warning dialog is displayed. If you want to install the Toolset integration, click More Options, and then click Always Install. If you do not want to install the Toolset integration, click More Options, and then click Never Install.
Topology Maps that were generated in previous versions of SolarWinds NPM may initially show links as red, due to the new interactive map settings.
Initial topology polling and calculations may require significant amounts of time for databases with more than 100,000 records.
Views Views by Device type keep switching to wireless access point view for Cisco devices.
Virtualization The Virtualization link on the Home menu bar is displayed for all users if a SolarWinds installation uses the default web console menu bar, even if account limitations intended to prevent access to the virtualization tab apply.

Known Orion Platform Issues

This version of SolarWinds Orion Platform includes the following known issues:

Area Description
Flow Navigator Flow Navigator displays nodes outside the scope of the account limitation.
Auto Dependencies Dependencies occasionally lose their topology links, which results in a reduced number of dependencies for nodes and alerts.
Alerting On an upgrade, the alert action Sending an SNMP Trap does not work correctly.
When editing an alert to consider a different object, the alert actions are executed twice.
Discovery Discoveries scheduled for a specific time do not run.
